Stacking Pressure-Driven Interfacial Dynamics in Anode-Free Solid-State Lithium Batteries. [PDF]
Adv Sci (Weinh)Using a three‐electrode setup, it is found that stacking pressure improves both anode and cathode interfaces but more effectively stabilizes the anode. Under low pressure, a sudden anode resistance rise indicates contact loss. Higher pressure delays this via Li creep and plastic deformation, maintaining interfacial contact.

Active Load-Sensitive Electro-Hydrostatic Actuator for More Electric Aircraft
Applied Sciences (Switzerland), 2020 In the flight control system, using an electro-hydrostatic actuator (EHA) instead of the currently used relatively mature electro-hydraulic valve-controlled actuator, there are three prevailing concerns, namely heating, size, and stiffness.
